Before this shop ever came to be, SALT. was the official SOP optics brand. I've personally worn their optics and sunglasses for over 3 years. For folks like me who wear their glasses always, comfort and quality are extremely important. SALT. strikes the perfect balance between style, durability, and fit. My first pair of daily wearers still looks brand new and has never needed a single adjustment. This is why I'm a lifer.
